TECHNICAL FIELD

Embodiments of this disclosure relate to the field of communications technologies, and in particular, to an information reporting method and a terminal.

BACKGROUND

During communication between a terminal and a network-side device, the terminal is required to perform radio resource management (RRM) measurement on a serving cell and neighboring cells to learn signal fading and signal quality between the terminal and the network-side device.

Currently, a network-side device configures an RRM measurement parameter for a terminal through radio resource control (RRC) signaling, and the terminal performs RRM measurement according to the configuration of the network-side device. It can be seen that, in the related art, the terminal depends on only the configuration of the network-side device to perform RRM measurement, which is not flexible.

It should be noted that the network-side device 12 is not limited to a specific type in the embodiments of this disclosure.

For ease of understanding, the following describes some content involved in the embodiments of this disclosure.

1. RRM Measurement Parameter

The RRM measurement parameter may include the following:

(1) Synchronization signal block measurement time configuration (SMTC): a first measurement frequency, a duration, a first measurement periodicity, a first reporting periodicity, an index of a measured synchronization signal/physical broadcast channel block (SSB), and the like.

The SMTC is a measurement time configuration for an SSB, and therefore, the duration, the first measurement periodicity, the first reporting periodicity, the index of a measured synchronization signal block (SSB) may be considered as configurations based on SSB measurement.

(2) Measurement object (MO): a cell, a beam, a second measurement frequency, a measurement resource, a second measurement periodicity, a second reporting periodicity, and the like.

The measurement resource, the second measurement periodicity, the second reporting periodicity may be considered as configurations based on measurement of the measurement resource. Optionally, the measurement resource may include an SSB and/or a channel state information (CSI)-RS, and the like. It should be understood that different resources for measurement may correspond to different cells and beams.

(3) Measurement threshold.

The measurement threshold may be understood as a threshold to trigger measurement on a target object, and the target object may be a second target cell, a target beam, or a target frequency.

The second target cell is a neighboring cell of the serving cell of the terminal. The target beam is a second beam other than the first beam. It should be understood that the first beam may be pre-determined, for example, may be pre-configured by a network-side device, or agreed in advance by the network-side device and the terminal.

The first beam may be beams of a same cell, or beams of different cells, and the second beam may be beams of a same cell, or beams of different cells. The target frequency is a frequency other than the frequency of the serving cell of the terminal.

Optionally, when an RRM measurement value (for example, a reference signal measurement value) is higher than the measurement threshold, the terminal does not need to perform measurement on a target object; otherwise, the terminal starts measurement on the target object. In this embodiment of this disclosure, the reference signal measurement value may be a reference signal received power (RSRP), a reference signal received quality (RSRQ), or the like.

For example, when a reference signal measurement value of the serving cell of the terminal is higher than the measurement threshold, the terminal may not need to perform measurement on the second target cell and the target frequency.

When a reference signal measurement value of a first beam is higher than the measurement threshold, the terminal may not need to perform measurement on the second beam.

2. Single Frequency Network (SFN) Measurement

A network system may be deployed in a manner shown in FIG. 2. As shown in FIG. 2, different cells may transmit physical channels or physical signals on a same time-frequency resource. For example, a plurality of cells may transmit broadcast information such as an SSB, Paging information and system information on a same time-frequency resource, that is, transmitting in an SFN mode. UE may transmit and receive broadcast information on a time-frequency resource of an SFN, including performing RRM measurement.

The following describes the information reporting method in this embodiment of this disclosure.

FIG. 3 is a flowchart of an information reporting method according to an embodiment of this disclosure. The information reporting method shown in FIG. 3 is applied to a terminal. As shown in FIG. 3, the information reporting method may include the following step: Step 301: Report assistance information for radio resource management RRM measurement to a network-side device, where the assistance information is used by the network-side device to determine an RRM measurement parameter for the terminal.

Optionally, in an implementation, the assistance information may be specifically used to request the network-side device to configure an RRM measurement parameter, so that the network-side device can perform more appropriate RRM measurement configuration for the terminal. In this implementation, after receiving a response message to the assistance information from the network-side device, the terminal may perform RRM measurement based on the response message.

In another implementation, the assistance information may be specifically used to inform the network-side device of an RRM measurement parameter determined by the terminal. In this implementation, the terminal may determine by itself an RRM measurement parameter for performing RRM measurement according to its own conditions and service requirements, and may directly perform the RRM measurement based on the determined RRM measurement parameter, without waiting for a response message to the assistance information from the network-side device.

The RRM measurement parameter in this step may include at least one of the RRM measurement parameters mentioned in the foregoing content.

It can be seen that in the information reporting method of this embodiment, the terminal may report assistance information for RRM measurement to the network-side device for the network-side device to determine an RRM measurement parameter for the terminal, so that the terminal can perform RRM measurement more flexibly.

In this embodiment of this disclosure, the terminal may actively report RRM measurement assistance information to the network-side device, or may report RRM measurement assistance information to the network-side device when it is detected that a specified condition is met.

Optionally, before the reporting assistance information for RRM measurement to a network-side device, the method further includes:

-   -   receiving indication information transmitted by the network-side         device, where the indication information is used to indicate         whether reporting of the assistance information is supported.

The reporting assistance information for radio resource management RRM measurement to a network-side device includes:

-   -   in a case that the indication information indicates that         reporting of the assistance information is supported, reporting         the assistance information to the network-side device.

Optionally, the indication information may be system information, RRC signaling, a medium access control-control element (MAC-CE) or downlink control information. This may be specifically determined according to actual needs, and is not limited in this embodiment of this disclosure. For example, the network-side device may indicate in system information whether reporting of assistance information by the terminal is supported.

After receiving the indication information indicating that reporting of assistance information by the terminal is supported, the terminal may report assistance information to the network-side device, so that the terminal can perform RRM measurement more flexibly.

It should be understood that in a case that the terminal receives indication information indicating that reporting of assistance information by the terminal is not supported, the terminal may quit reporting assistance information to the network-side device, so that signaling overheads can be reduced.

In this embodiment of this disclosure, in a case that the assistance information may be specifically used to request the network-side device to configure an RRM measurement parameter, optionally, the assistance information may include at least one of the following:

-   -   first request information for requesting configuration of an RRM         measurement parameter;     -   capability information of the terminal under a single frequency         network; and     -   a mobility state of the terminal.

It should be noted that the first request information is intended to request the network-side device to configure an RRM measurement parameter, but specific content contained in the first request information is not limited in this embodiment of this disclosure.

Optionally, the first request information includes or does not include the RRM measurement parameter.

First scenario: An RRM measurement parameter is included in the first request information.

In this scenario, an RRM measurement parameter is carried in the first request information, and therefore, the first request information may be specifically used to request the network-side device to perform RRM measurement parameter configuration according to the RRM measurement parameter carried in the first request information.

Second scenario: No RRM measurement parameter is included in the first request information.

In this scenario, the first request information may be used to request the network-side device to reconfigure an RRM measurement parameter, to reduce power consumption of the terminal in performing RRM measurement.

It should be understood that because no RRM measurement parameter is carried in the first request information, in this scenario, the network-side device determines by itself a reconfigured RRM measurement parameter, with a purpose of reducing power consumption of the terminal in performing RRM measurement.

Optionally, the first request information may only carry bit information used to request the network-side device to reconfigure an RRM measurement parameter.

It can be seen that compared with the first scenario, the first request information in the second scenario may not carry an RRM measurement parameter, and resource occupancy is low, so that signaling overheads may be reduced. In addition, the network-side device determines by itself a reconfigured RRM measurement parameter, with a purpose of reducing power consumption of the terminal in performing RRM measurement, so that power consumed by the terminal in performing an RRM measurement can be reduced.

Compared with the second scenario, an RRM measurement parameter in the first scenario is carried in the first request information, the network-side device may configure a parameter related to the RRM measurement parameter, so that the network-side device may perform more appropriate RRM measurement configuration for the terminal, thereby improving accuracy of the measurement, or reducing unnecessary measurements to reduce measurement power consumption.

Further, the first request information may include at least one of the following:

first sub-request information for requesting configuration of a synchronization signal block measurement time configuration SMTC, where the SMTC includes at least one of a duration, a first measurement periodicity, a first reporting periodicity, an index of a measured synchronization signal block SSB, and a first measurement frequency;

-   -   second sub-request information for requesting configuration of a         measurement object, where the measurement object includes at         least one of a cell, a beam, a measurement resource, a second         measurement frequency, a second measurement periodicity, and a         second reporting periodicity; and third sub-request information         for requesting configuration of a measurement threshold.

It should be noted that for the sub-request information in the first request information, specific content of the sub-request information is not limited in this disclosure. In the implementation, the sub-request information may include or not include a parameter that is requested to be configured for the sub-request information, such as an SMTC, a measurement object, and a measurement threshold. This may be specifically determined according to actual needs, and is not limited in this embodiment of this disclosure.

For the first sub-request information, it should be understood that the parameter included in the SMTC such as a duration, a first measurement periodicity, or a second reporting periodicity is related to an SSB.

For the second sub-request information, the parameter included in the measurement object such as a second measurement periodicity or a second reporting periodicity is related to a measurement resource. It can be learned from the foregoing content that the measurement resource may include at least one of an SSB and a CSI-RS.

The following describes specific functions of each sub-request information.

Optionally, in a case that the assistance information includes the second sub-request information, the second sub-request information is used to request a first target cell in first cells to serve as a new measurement cell, where

-   -   a reference signal measurement value of the first target cell is         higher than reference signal measurement values of other cells         in the first cells different from the first target cell, and the         first cells are cells configured by the network-side device         and/or cells detected by the terminal.

In the implementation, before reporting assistance information for radio resource management RRM measurement to a network-side device, the terminal may determine the first target cell in the first cells.

Optionally, the terminal may determine the first target cell in the first cells through at least the following two methods.

Method 1: The terminal may determine a cell in first cells with a reference signal measurement value higher than a preset threshold as a first target cell. The preset threshold may be pre-configured by the network-side device.

It should be noted that in a practical application, the terminal may determine a first target cell based on a plurality of measurement results. For example, if the terminal collects m measurement results, a cell whose reference signal measurement values in n measurement results are all higher than a preset threshold in the first cells can be determined as the first target cell, where m and n are both natural numbers, and n is less than m. Optionally, n may be a natural number greater than m/2 and less than m, but is not limited thereto.

Method 2: The terminal may determine k cells with largest reference signal measurement values in first cells as first target cells, where k may be configured by the network-side device, or agreed in advance by the network-side device and the terminal. This may be specifically determined according to actual needs, and is not limited in this embodiment of this disclosure.

It should be noted that in a practical application, the terminal may determine a first target cell based on a plurality of measurement results. For example, the terminal may compare average values of reference signal measurement values of cells in the first cells in a plurality of measurement results, and determine k cells with largest average reference signal measurement values in the first cells as first target cells. However, this is not limited thereto.

In this implementation, in a case that the network-side device accepts the request in the second sub-request information, the terminal may perform measurement only for the first target cell in subsequent RRM measurement, thereby reducing power consumption of the terminal.

Optionally, in a case that the assistance information includes the second sub-request information, the second sub-request information is used to request a target measurement resource in first resources for measurement to serve as a new measurement resource, where

-   -   a reference signal measurement value of the target measurement         resource is higher than reference signal measurement values of         other resources for measurement in the first resources for         measurement different from the target measurement resource, and         the first resources for measurement are resources for         measurement configured by the network-side device and/or         resources for measurement detected by the terminal.

In the implementation, before reporting assistance information for radio resource management RRM measurement to a network-side device, the terminal may determine a target measurement resource in the first resources for measurement.

Optionally, the terminal may determine the target measurement resource in the first resources for measurement through at least the following two methods.

Method 1: The terminal may determine a measurement resource with a reference signal measurement value higher than a preset threshold in first resources for measurement as a target measurement resource. The preset threshold may be pre-configured by the network-side device.

Method 2: The terminal may determine k resources for measurement with largest reference signal measurement values in first resources for measurement as target resources for measurement, where k may be configured by the network-side device, or agreed in advance by the network-side device and the terminal. This may be specifically determined according to actual needs, and is not limited in this embodiment of this disclosure.

It should be noted that a principle of determining a target measurement resource is similar to a principle of determining a first target cell. For details, refer to the foregoing description of determining a first target cell. Details are not described herein.

Further, in a case that the number of the target resources for measurement is greater than 1, the target resources for measurement are resources for measurement of a same cell, or the target resources for measurement are resources for measurement of different cells.

In this implementation, in a case that the network-side device accepts the request in the second sub-request information, the terminal may perform measurement only for the target resources for measurement in subsequent RRM measurement, thereby reducing power consumption of the terminal.

Optionally, in a case that the assistance information includes the second sub-request information, and the measurement object includes the second measurement periodicity and/or the second reporting periodicity, the second sub-request information is used to request to extend the second measurement periodicity and/or the second reporting periodicity.

In a practical application, if the terminal detects that communication quality between the terminal and the network-side device has not changed much, for example, the terminal is in low mobility, or the terminal is moving in a strong signal coverage area of the serving cell, the terminal may request the network-side device to configure a longer measurement periodicity and/or reporting periodicity, so that the number of measurements and/or the number of reports performed by the terminal may be reduced, thereby reducing power consumption of the terminal.

Optionally, the second sub-request information may carry or not carry a specific measurement periodicity or reporting periodicity recommendation.

Optionally, in a case that the network-side device pre-configures a first measurement threshold, and the assistance information includes the third sub-request information, the third sub-request information is used to request to lower the first measurement threshold, and/or the third sub-request information is used to request to add a second measurement threshold, where the second measurement threshold is lower than the first measurement threshold.

It can be learned from the foregoing content that the measurement threshold is a threshold to trigger measurement on a target object. Optionally, when a reference signal measurement value is higher than the measurement threshold, the terminal does not need to perform measurement on a target object; otherwise, the terminal starts measurement on the target object. For description of the target object, reference may be made to the foregoing content. Details are not described herein again.

Therefore, if the terminal needs to reduce the frequency of starting measurement on a target object, the terminal may request the network-side device to lower the first measurement threshold. In this way, the probability that the reference signal measurement value of the terminal is higher than the lowered first measurement threshold increases, making it harder for the terminal to start measurement on the target object.

It should be noted that when the third sub-request information is used to request lowering of the first measurement threshold, the third sub-request information may include or not include: a lowered first measurement threshold or a first measurement threshold change value.

If the terminal needs to reduce the number of target objects to be measured, the terminal may request the network-side device to add a second measurement threshold that is lower than the first measurement threshold. The terminal does not need to perform measurement on the target object when the reference signal measurement value is higher than the measurement threshold, and the second measurement threshold is lower than the first measurement threshold. Therefore, it can be understood that for the first scenario in which the reference signal measurement value is lower than the first measurement threshold and higher than the second measurement threshold, and the second scenario in which the reference signal measurement value is lower than the second measurement threshold, the number of target objects to be measured in the first scenario is less than the number of target objects to be measured in the second scenario.

In this way, in a scenario in which the reference signal measurement value is lower than the first measurement threshold and higher than the second measurement threshold, the terminal may start measurement on a target object, but in this case, the number of target objects to be measured is less than the number of target objects to be measured in the second scenario, so that the number of target objects to be measured is more flexible, reducing measurement power consumption.

It should be noted that when the third sub-request information is used to request addition of a second measurement threshold, the third sub-request may include or not include the new second measurement threshold.

In addition, the number of new second measurement thresholds may be determined according to actual needs, and is not limited in this embodiment of this disclosure.

Furthermore, different target objects may correspond to different measurement thresholds, for example, an S-measure threshold for triggering measurement on a second target cell, and a B-measure threshold for triggering measurement on a target beam.

It can be learned from the foregoing content that the terminal may perform RRM measurement on a time-frequency resource of an SFN. It is well known that when the terminal performs RRM measurement on a time-frequency resource of an SFN, measurement power consumption may be reduced compared with performing RRM measurement on a measurement resource of a non-SFN. Therefore, in this embodiment of this disclosure, assistance information may include capability information of the terminal in an SFN for indicating whether the terminal has an information reception capability under the single frequency network, so that the network-side device may determine whether to configure an SSB, a CSI-RS, or other RS resources to be transmitted in an SFN form for UE to perform RRM measurement, and determine whether to transmit paging information, a broadcast signal, and broadcast information in an SFN form.

Optionally, in a case that the assistance information includes the capability information, and the capability information indicates that the terminal has an information reception capability under the single frequency network, the assistance information further includes second request information, where the second request information is used to request the network-side device to perform transmission of a broadcast signal, broadcast information, and paging information under the single frequency network.

Optionally, in a case that the terminal has an information reception capability under the single frequency network, the terminal may request the network-side device to perform measurement configuration under the SFN and transmission of paging information. In this way, the terminal may transmit and receive paging information, SSBs and other downlink broadcast signals based on SFN resources configured by the network-side device, thereby reducing measurement power consumption.

In this embodiment of this disclosure, RRM measurement is mainly used to measure signal quality between a terminal and a network-side device, and for a terminal in a resting or low mobility state, it is not necessary to perform RRM measurement too frequently. Therefore, the assistance information may include a mobility state of the terminal, so that the network-side device may configure, based on the mobility state of the terminal, an RRM measurement parameter for the terminal to perform RRM measurement, thereby reducing power consumption of the terminal.

In this embodiment of this disclosure, the terminal may determine its own mobility state in a plurality of ways. Optionally, the mobility state is determined according to at least one of the following: a direction of arrival (DOA) measurement result, a measured RS timing offset, a Doppler measurement result, and measurement information corresponding to a satellite communications system, but is not limited thereto.

It should be noted that various optional implementations described in this embodiment of this disclosure may be implemented in combination or may be implemented independently, which is not limited in this embodiment of this disclosure.

The information reporting method in this embodiment of this disclosure may include:

1. UE transmits at least one of the following RRM measurement-related assistance information to a network-side device:

-   -   a) a request SMTC configuration, an SMTC duration, and an index         of a measured SSB.     -   b) MO information requested to be configured by the network-side         device, and an MO configuration requested to be configured by         the network-side device:         -   a cell index, a beam index, a measurement RS resource index,             and an MO configuration index, where         -   the MO information may be understood as recommendation             information, and may carry no RRM measurement parameter; and             the MO configuration may carry an RRM measurement parameter.     -   c) a measurement periodicity and a reporting periodicity         requested to be configured.     -   d) the number of cell- or beam-level S-measure thresholds and         threshold values requested to be configured; the number of         neighboring cells and the number of neighboring frequencies to         be measured.     -   e) whether the UE has a reception capability under an SFN         network, which is reported to the network-side device by the UE.

When the UE has the reception capability under the SFN network, the UE may request the network-side device to perform measurement configuration under the SFN network and perform transmission of paging information.

2. The network-side device indicates in system information, RRC signaling, a MAC-CE or a downlink control channel whether reporting of the assistance information by the UE is supported.

For ease of understanding, the following examples are described.

Embodiment 1

After a long-term measurement, the UE finds that cell0, cell1, and cell2 are cells with the best indicators such as RSRP and RSRQ for a relatively long period of time. However, the network side device has configured measurements on cells 0 to 6.

The UE transmits feedback information to the network-side device, indicating to the network-side device that measurements on cell0, cell1, and cell2 continue, and measurements on cells 3 to 6 stop.

Embodiment 2

After a long-term measurement, the UE finds that SSB0 and SSB2 of the current serving cell are resources for measurement with the best indicators such as RSRP and RSRQ for a relatively long period of time. However, the network side device has configured measurements on SSBs 0 to 4.

The UE transmits feedback information to the network-side device, indicating to the network-side device that SSB0 and SSB2 are still used as resources for measurement, and measurements on SSB1, SSB3, and SSB4 stop.

Embodiment 3

After a long-term measurement, the UE finds that SSB0 of cell0 and SSB1 of cell1 are resources for measurement with the best indicators such as RSRP and RSRQ for a relatively long period of time. However, the network side device has configured measurements on SSB0 to SSB4 of cells 0 to 4.

The UE transmits feedback information to the network-side device, indicating to the network-side device that SSB0 of cell0 and SSB1 of cell1 are still used as resources for measurement, and measurements on SSBs of other cells stop.

Embodiment 4

The UE transmits feedback information to the network-side device, expecting lowering an S-measure threshold, to make it harder to start neighboring cell measurement. The request information or requested S-measure threshold may be transmitted.

The UE transmits feedback information to the network-side device, expecting reduction of the number of neighboring cells to be measured. The UE may request the network-side device to configure another S-measure2 threshold. If the S-measure threshold is not met, but the S-measure2 threshold is met, X neighboring cells are to be measured. If the S-measure2 threshold is not met, all configured cells or cells detected by the UE are measured. It should be understood that the number X of neighboring cells is less than the number of configured cells or cells detected by the UE.

In this embodiment, the S-measure thresholds are RSRP and RSRQ thresholds for cell-level measurement, and target objects are target cells, that is, neighboring cells of the serving cell of the terminal.

Embodiment 5

It is assumed that the measurement threshold is a threshold to control the number of RS-level measurements. A higher threshold means fewer RS measurements to be performed, and generally beams corresponding to an RS may be different, that is, fewer beams are to be measured. For example, when measurement values of N optimal beams such as RSRP and RSRQ are higher than corresponding thresholds, no measurement on other beams is performed; otherwise, measurements on other beams are started. In this embodiment, the threshold is described as a B-measure threshold. In this embodiment, the B-measure thresholds are RSRP and RSRQ thresholds for RS-level measurements, and target objects are target beams. It should be noted that the foregoing N beams can be understood as the first beam in the foregoing content.

The UE transmits feedback information to the network-side device, expecting lowering a threshold in the B-measure that triggers a target beam measurement, to make it harder to start a target beam measurement. The request information or requested B-measure threshold may be transmitted.

The UE transmits feedback information to the network-side device, expecting reduction of the number of neighboring beams to be measured. The UE may request the network-side device to configure another B-measure2 threshold. If the B-measure threshold is not met, but the B-measure2 threshold is met, X neighboring beams are to be measured. If the B-measure2 threshold is not met, all configured beams or beams of the cells detected by the UE are measured. It should be understood that X is less than the number of configured beams or beams of the cells detected by the UE.

In this embodiment, whether the X beams or N beams come from a same cell is not limited. In other words, the X beams may be beams of a same cell, or may be beams of different cells, and the N beams may be beams of a same cell, or may be beams of different cells.

Embodiment 6

The UE transmits a request to extend a measurement periodicity and a reporting periodicity to the network-side device, or transmits a specific measurement periodicity or reporting periodicity recommendation to the network-side device.

Embodiment 7

Whether the UE is in a low mobility state is fed back to the network-side device.
